You could look into using scripts with tools like acpi
or upower
. A simple shell script checking battery levels every few minutes could work: if it’s below 20%, play a sound. Schedule it with a cron job or a systemd service for consistency. I’m no script guru, but there’s lots of good examples online!
Owncloud Infinite Scale definitely has speed going for it! But yea, the lack of customization can be a letdown. As for plugins, the community is still in its early stages compared to Nextcloud. Might have to roll up your sleeves and contribute some plugin development if you’re up for it! Also, you could poke around the GitHub repo - sometimes early-stage projects have hidden gems in the issue tracker or branches.
